UPDATE: Moved the "mariobmp" to a seperate .h (mariobmp.h) file and load the graphic by a call. Very nice as how it frees up having to see a top of ASM code in the Arduino IDE.

And Yes, I drew the pic in the Gimp, it is an 84x48 black and white BMP file, done the old fashioned way, Pixel by Pixel.

The final plan for this thing is for me to get a working Pong on this thing... See that one small button in the bottom left hand side? Thats a "5 degrees of freedom" button, AKA a mini-primitive joystick. the 5th "degree" is actually pushing in the stick, you know, like a button.

Actually I meant making a quick program with your own RLE in it. I recently worked out a form of compression for animated sprites that used my own brand of RLE, along with some other things; I ditched it after discovering that PNG still had it beat, though.

MNG was the file extension, if I recall. GIMP supports it still, and so did some browsers for a while. APNG was an unofficial version to further the effort; Firefox supports it even now, and Chrome can handle it with an APNG plugin. I agree it's a shame, but I must admit that animated images are pretty passť compared to general multimedia like Flash and HTML5.

Anyway, You could try endless racer game (avoid appearing obstacles), it's easy to code (I mean technical-logical aspect, I see it as array of boolean arrays progressed with timer - where You only have to check slot where player is for collision)
